Azure: How to move messages from poison queue to back to main queue?

Question

I\'m wondering if there is a tool or lib that can move messages between queues? Currently, i\'m doing something like below

public static void ProcessQueueMes

As at (2018-09-11) version 1.4.1 of the Microsoft Azure Storage Explorer doesn’t have the ability to move messages from one Azure queue to another.

I blogged a simple solution to transfer poison messages back to the originating queue and thought it might save someone a few minutes. Obviously, you'll need to have fixed the error that caused the messages to end up in the poison message queue!

You’ll need to add a NuGet package reference to Microsoft.NET.Sdk.Functions :

using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Queue;

void Main()
{
    const string queuename = "MyQueueName";

    string storageAccountString = "xxxxxx";

    RetryPoisonMesssages(storageAccountString, queuename);
}

private static int RetryPoisonMesssages(string storageAccountString, string queuename)
{
    CloudQueue targetqueue = GetCloudQueueRef(storageAccountString, queuename);
    CloudQueue poisonqueue = GetCloudQueueRef(storageAccountString, queuename + "-poison");

    int count = 0;
    while (true)
    {
        var msg = poisonqueue.GetMessage();
        if (msg == null)
            break;

        poisonqueue.DeleteMessage(msg);
        targetqueue.AddMessage(msg);
        count++;
    }

    return count;
}

private static CloudQueue GetCloudQueueRef(string storageAccountString, string queuename)
{
    CloudStorageAccount storageAccount = CloudStorageAccount.Parse(storageAccountString);
    CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();
    CloudQueue queue = queueClient.GetQueueReference(queuename);

    return queue;
}
